Purely informational, this one. My sister bought the little guidebook when we went camping in a nearby national park, last month. I'm particularly wary of ticks since the county I live in has one of the highest incidents of lyme disease in the nation, I personally know two people who have contracted the disease, and my kids have gotten ticks on them four times since we moved here. The cat occasionally comes home with a tick on him, as well. This little book is dense with information, written in a clear format. I learned about the life cycle of ticks and when they are likely to carry the disease and transmit it to humans. I learned more about their behavior- particularly that they don't drop from trees but climb up stems of grass or brush and then grab onto you as you walk past. They will climb up your body, which is why you find them on your head. I learned more about how to prevent tick bites, how to treat them, and when to worry about the disease (not quite as much of a risk as I had feared). The book also has information on a myriad of other diseases ticks can harbor, and other small critters that can give dangerous bits or stings such as scorpions, black widow spiders and chiggers. I have certainly been educated.
